rnnronar'me-nacnmnj To all whom it may concern:

Be itknown that I LOUIS W. G. FLYNT, a subject of the King of GreatBritain, residing at Rochester, in the county of Mom roe and State ofNew York, have inventedcertain Improvements in Perforating-Machines, ofwhich the following description, inconneetion with the accompanyingdrawings, is a specification, like reference charactors on the drawingsindicating like pa-rts'in the several figures.

This invention relates to punching niachines, and articularly topunching machines for forming. ornamental perforations in stock, such,for example, as toe-caps and other parts of boots and shoes. Themachines whichoare generally used for this purpose are provided with apunch which penetrates the stocnintermittingly, a presser foot whichengages the stock at apoint at one side of the line in'which theperforations are being formed, and mechanism for feeding the stock tobring different portions of it successively into position to be actedupon by the punch. For forming perforations in a curved or irregularline the stock is turned relatively to the direction in whichit is beingfed, and the fulcrum about. which it is turned is the presser foot.Machines of this tynnihave not proved satisfactoryforforminw'perforations in both straight and curved "lines because thespaces between the perforati'ons formed in a curved line are not of thesame length as those between the perforations formed in a straight line.1 This is due to the fact that the point about which the stock is turnedis located at one side of the line in which the perforations are formed,so that when the stockiis turned about the presser foot in onedirection'to. produce a curved line of perforations the point at whichthe last perforation was made will'bev moved slightly in the directionin which the stock is being fed, thereby increasing the length of thespaces between t perforations, and when. it isftu'rne'd about thepresser foot in the other direction that point .will be movedslightly-in the opposite direction to that in which the stock is bein'gfed, thereby decreasing thelength of the spaces between theperforations.

The chief'- bject of this invention is to provide means for insuringthat the spaces between perforations formed'in a curved or Specificationof Letters Patent. Patented NOV. 30, 1909. Application filed January.31, 1905. Serial-No. 243,504.

irregular line will be of the same length as those between perforationsformed ,in a straight line and to this end I have devised a punchingmachine having a presser foot which engages the stock at 1 point inalinement with the line of perforations formed in the stock, so thatwhen the stock is turned about the presser foot, the point at which thelast perforation was made will not be moved either in the same or in thereverse direction to that in which the stock is being fed but will bemoved at approximately a .right angle to the direction of the feed.

I have herein shown the preferred form of my invention as embodied in amachine having a punch which penetrates the stock and then moveslaterally for feeding the stock, the stock being engaged at a point inthe plane of lateral movement of the punch by a presser foot which ismoved automatically into and out of operative position. In order thatthe punch may penetrate-the stock without being subjected to contactwith a hard metallic bed. surface, a facing strip of soft and preferablyflexible material is interposed between the punch block and the stockbeing .operated on, said strip being moved step by sfip as the stock isfed, so that a fresh portion-of the strip will be presentedto the puncheach time penctrates the stock, and one of the features of thisinvention consists in' means for guiding said strip in its movement and,when flexible, for winding it into a coil as it passes from the punchblock.

Other features of the invention consist in an adjustable worlcgage whichcan be depressed below the surface of the stocksupporting table whensaid gage is not in use, novel mechanism for moving the punch laterally,and for varying the extent of reciprocating movement of the punch, andimproved means for changing the degree of lateral movement of the punch.

In the drawings, which illustrate the preferred form. of the invention,Figure 1 is a side elevation-of a' punching machine enibodying featuresof my invention; Fig. 2 is an elevation of the left-hand end ofthemachineshown in Fig. 1; Fig. 3 is a plan view, partly in section, takenon the line y-. z of Fig. 2, showing the cams on the main shaft foractuating the punch, punch carrier, and presser foot bar; Fig. 4 is aview, partiy in section, of the punch bar, punch carrier, and themechanism for moving it laterally; Fig. 5 is a detail side elevation,partly in section, taken on the line ar -m of Fig. 2, showing the camson the main shaft and the mechanism for adjusting the roller on the endof the punch. bar; Fig. 6 is a side elevation of the presser foot andthe mechanism for moving it relatively to the presser foot bar; Fig. 71s a perspective view of the W0] k-gage against which the stock is held;Fig. 8 is a perspective view of the spools on which the facing strip isWound when flexible and the standard on which said spoolsare mounted;Figs. 9 and 10 are perspective detail views of said spools with theretaining plates removed; Fig. '11 is a detail sectional View showingthe means for imparting movement to the shaft which carries one of thespools; and Fig. 12 is a vertical sectional view taken through thestock-supporting table showing the means for guiding the facing stripwhen flexible.

Referring to the drawings, 2 designates a frame which carries a mainshaft 4 having a driving pulley 5 and provided with a cam 6 fordepressing a punch bar 8 and with cams 10 and '12 for imparting lateralmovement to a carrier 14 in which the punch bar is mounted. The mainshaft is mounted in bushings 100 and 101 inthe frame, and the carrier 14is provided at its upper end with straps 15, 15 that are journaled onsaid bushings, as shown in Fig. 5, and pivotally connected toa bracket16 on said carrier is a lever 18. provided with rollers 20 and 21 whichcooperate with the cams 10 and 12 on the 1nain shaft. A fulcrum block 22is ad just'ably mounted in a slot 23 in a stationary part of the frameand is provided with a roller 25 which acts as a fulcrum for the lever18, so that when the upper end of said lever is moved outwardly by thecams on the main shaft the lower end of said lever will be moved in theopposite direction, thereby swinging the punch bar carrier 14: in thedirection of the arrow in Fig. dfor causing the punch to feed the stock,said carrier being moved in the opposite direction, back to startingposition, by a spring 11 confined in a stationary part of the frame andbearing against said carrier. By changing the position of the fulcrumblock the extent of movement of the punch bar carrier in each directionwill'be varied and the distance which the punch feeds. the stock will bechanged. The punch bar is provided at its upper end with ears 7 and 7 inwhich a pin 26 is mounted, said pin having an eccentric portion whichcarries a roller/2T that cooperates with the cam (5 that depresses thepunch bar, said bar being moved upwardly to withdraw the punch from thestock by means of a spring 9 that surrounds said bar, as shown in Fig.4.

A headed bushing-17 surrounding a portion of the pin 26 is threaded intothe ear 7 of the punch bar and extends outwardly through a slot 19 inthe upper end of the carrier 14, and surrounding the extended portion ofsaid bushing is the hub 31 of a- .and said punch may consist of a singlehollow punch tube or of a plurality of hollow punch tubes, as shown inFig. 4, depending upon the style of perforations which are to be formedin the stock, the pieces of punchedout material. passing up through anopening in the punch bar and out of a chute 36 fastened to the carrier14.

, A presser foot 40 is conveniently secured, as by a screw 89, to ablock 43 slidingly mounted in a bearing 45 on the lower end of a.presser foot bar 41-2 which is mounted in the central longitudinal planeof the machine and which isconnected at its upper end to an elbow lever44 pivoted to a stationary part of the frame and provided with a roller16 that is engaged by a cam 48 on the main shaft for moving the presserfoot bar up.

wardly, the presser f0 t bar being moved downwardly by a coi ed spring47 which surrounds said bar between a shoulder there on and a stationarypart of the frame, as shown in dotted lines in Fig. 1. As shown in Fig.1, the presser foot is adapted to engage the stock at a point directlyin the path in which the punch moves laterally for feeding the stock, sothat when the stock is turned about the presser foot to produce a curvedor irregular line of perforations the point at which the lastperforation was made will be moved at approximately a right angle to thedirection in which the stock is being fed, the fulcrum about which thestock is turned being located in the same vertical plane as that inwhich the punch moves laterally. The presser foot is preferably providedwith a contact face which is shaped to engage a small portion only ofthe stock at a point in alinement with the perforations being formed.The stock may thus be turned readily about the presser foot as a centerand without liability of producing unequal spacing between theperforations. The block 43 which carries the presser foot is connectedby a pin 11 to the end of an actuating lever 50 mounted in the presserfoot bar, which may be slotted to receive it, and pivotally connected at51 to a sleeve 52 on said bar, the movement of said block in its bearingbeing ing plate 77 being fastened to said stud. The strip passes under aguide roller 78 mounted on a stud 7 9 carried by the standard, through aguideway formed by a Hat tube 80 mounted on the frame of thema chinebelow the table, over a guide roller 82 mounted at the end of said tubeand thence in the opposite direction through a tube 83 extendingparallel to tube 80. From the tube 83 the strip passes up through a slot81 formed in the table, over the punch block 3, and then below thesurface of the table through a slot '85 to a guide roller 84 mounted onthe stud 79, and from said roller up to a receiving spool 86 which isfastened to a shaft 88 carried by the standard 76. The receiving spool86 is ,rovided with a slot 87 in which the end 0 the strip is inserted,said strip being confined between the retaining plate 89 and cooperatingplate 97 pro vided with a socket 98 which receives the split end ofshaft 88, as shown in Fig. 9.

-A pulley 90 is loosely mounted on shaft 88-and is driven by means ofabelt 91 that passes over a pulley 92 on the main shaft, the pulley 90being confined between two friction washers 93 and 94 splined to theshaft 88. A coiled spring 95 surrounds the shaft 88 between washer 94and a nut 96 on said shaft and operates to force said friction washersand pulley into engagement with each other for causing rotary movementto be imparted to said shaft. The tension of spring 95 can be varied byadjusting the nut 96 and in practice the tension of said spring is soregulated that it W111 cause rotary movement to be'impar ted to shaft 88only when the punch is feeding the stock and the strip, thereby takingup the slack in the strip.v After the strip has passed throughthemachine once and has been wound into a coil on the jSpOOl 86, thecoil is removed from said spool and is again placed on the stud 33, thecoil beingreversed so that the opposite edge of the strip will-be actedupon by the punch when it is again fed through the machine.

In order that the strip 7 2 may be used .a number of times, the guidewayformed by the tubes 80 and 83 is adapted to beadjustr ed transversely ofthe punch blockso that different portions of the width of the strip canbe brought into position to be acted upon by the punch, said tubes beingfastened to a block 99 which is engagedby the'threaded end of anadjusting screw 177 rotatably mounted in upwardly projecting lugs 37,37' on the base of the machine.

The operation of the machine is as follows: As the main shaft revolves,the cam 6 forces thepunch through the stock and into the stri offlexible material which is in'terosed etween the strip andthe punchlock.- Thereafter. the punch retracted slightly but is not withdrawnfrom the stock or strip, and the cams l0 and 12 op erating upon thelever 18 swing the punch carrier laterally in the direction of the arrowin Fig. 4 for causing the punch to feed the stock and also the strip offlexible material, said stripl being wound onto the spool 86 asit is festep by step with the stock. When the punch arrives at the end of itslateral movement, the-presser foot bar moves downwardly and the spring58 moves the presser foot 40 into position to engage the stock at apoint in alinement with the line of perforations being formed in thestock,

the presser foot remaining in engagement with the stock while the punchis being withdrawn from the stock and strip by the spring 9 surroundingthe punch bar, and moved back to starting position by the spring 11acting upon the punch bar carrier.

As the punch is again forced into the stock the cam 48, operating onlever 44, moves the presser foot bar upwardly and during the upwardmovement of the presser'foot bar the toe 54 on lever 50 comes intoengagement with the stop 56, thereby rocking said lever and moving thepresser foot in the direction of the arrow in Fig. 6 out of-the path oflateral movement of the punch. These operations are repeated forformingsuccessive perforations in the stock, and so long as the stock is notturned about the resser foot the perforations will be forme ina straightline. By turning the stock about i I the presser foot as a fulcrum, thepoint'a-t which the last perforationwas made will bemoved atapproximately a right angle to the direction in which the stock is beinfed and a different portion of the stock wilfbe moved into alinementwith the punch, so that the next perforation which is formed will be outof alinement with those formed in a straight line, the operatorcontinuing to turn the stock after each-feed movement so as to form acurved or'irregular line of perforations.
